Abstract
A tracking system is provided. The tracking system includes a three degree-of-freedom (3DoF) device, a camera, and a processor. The 3DoF device is adapted to be mounted on a control device worn or hold on a body portion of a user. The 3DoF device is configured to obtain sensor data from a 3DoF sensor of the 3DoF device. The camera is configured to obtain camera data. The camera data comprises an image of the body portion of the user or the control device as a tracking target. The processor is configured to: track the tracking target to generate a tracking result based on the sensor data and the camera data; determine the tracking target being static or not based on the tracking result; determine a target pose of the tracking target based on the tracking result; and calibrate an accumulative error of the 3DoF sensor in background.
